Go language remainder calculation

In the Go language, use the % remainder operator to calculate the remainder, which returns the remainder after the dividend minus the quotient multiplied by the divisor. For example, calculating the remainder of 100 divided by 7 yields 2.

Remainder calculation in Go language

In Go language, the remainder operator can be used to calculate the remainder% . This operator returns the remainder of the dividend minus the quotient multiplied by the divisor.

Syntax:

result := dividend % divisor

Among them:

• dividend is the dividend
• divisor is the divisor
• result is the remainder

Practical case:

Write a program to calculate Remainder when 100 is divided by 7:

package main

import "fmt"

func main() {
    dividend := 100
    divisor := 7
    result := dividend % divisor

    fmt.Printf("100 除以 7 的余数是: %d\n", result)
}

Output:

100 除以 7 的余数是: 2

In this example, the program calculates the remainder when dividend is divided by divisor and Store it in the result variable. Finally, the program prints the remainder 2.

Note:

• If the divider is zero, a runtime error will occur. Therefore, it is important to verify that the divisor is non-zero.
• The remainder operator has lower precedence, so if you need to remainder a complex expression, you can use parentheses.
